Emma Charles is the 30 year old granddaughter of Nick and Nora Charles, the high society sleuthing couple immortalized in "The Thin Man" movies of the 1930s. Emma's dream of following in her grandparents' footsteps has started to come true: she has opened her own private investigation agency and secured her first case with a high profile client. The second part of Emma's dream is more elusive: enjoying the kind of romance that Nick and Nora made famous. Emma's devotion to her grandparents' Swing Era culture has made it impossible to find a contemporary man who can match her wit, taste and love of jazz music and gin martinis. But as Emma tackles her first case, which has unexpectedly implicated her client's wife, she meets Dash Moran, a jazz pianist who has big dreams of his own and also harbors a deep appreciation for that bygone era. In this stylish mystery/romance that races from the posh Upper East Side of Manhattan to funky Harlem and out to the glittering mansions of the Hamptons, Emma joins forces with Dash and an unforgettable cast of characters to solve a series of murders that threaten to make Emma and her client's wife the final victims.
